Perturabo
Primarch of the Iron Warriors.
Greatly known for his mastery of siege warfare. He is feared for his status as a Daemon Prince, and his Rage, which is mainly due to an itch to the back of his head that he cant scratch due to the cable wiring (refer to the picture on the right). In other words, he's one big, mean and badass motherfucker who knows how to make the strongest thing go down.
At the time of the Great, Great Crusade, Perturabo was a busy boy, building citadels and forts on the planets that he conquered, leaving always a little of his forces behind. In the end it became a steroetype that the Iron Warriors had the best army for sieges ( I bet Matt Ward Will eventually change that in the fluff). He was also kept far away by the other Primarchs, mainly because Perturabo had so much badass technology they did not possess. Peturabo had a big hard on for Leonardo Da Vinci and spent much time searching the ruins of Old Earth for copies of his surviving journals, gathering his hidden papers and learning of the works he pursued in private.
Whats also known about him is his rivalry with Rogal Dorn. What we know about these two is that their quarrels were equivalent to the typical sibling rivalry. While Dorn's Daddy's Golden boy, Perturabo serves as the incredibly jealous brother who just wants to tear his brother limb from limb. Another reason why he was jealous of Dorn was due to Peturabo considering himself an architect and builder but was left destroying everything instead while Dorn did what he wanted to be doing. The most iconic incident occurred when Fulgrim asked Dorn if he could build a fortress that Perturabo couldn't crack; Dorn answered "Yes" and Perturabo threw a fit and left. Dorn also said this of Peturabo, '‘Perturabo throws men at walls, If the Araakites (opponents of that campaign) so much as thought a wall he would pelt it with our legionaries as if there were no other way.’ He also had an inferiority complex and was greatly pressured when he and his Legion were relegated to garrison duty. They became so frustrated that they vented their frustrations by slaughtering everyone in their own homeworld when it had revolted.
Also, every last one of his brothers treated him like shit and called him a stupid hick (except Sanguinius, best of men). He held it all in for a long, long time, until, after a grueling three-part campaign in which the Iron Warriors, Blood Angels, and Imperial Fists all ganged up on a Fortress World, Rogal Dorn was given a medal, Peturabo was given nothing, and a master artist showed him a master-work of a painting depicting the battle, in which the Imperial Fists won a heroic victory while the Iron Warriors were literally ground face-first into the mud. And that, as they say, was the straw that broke the camel's back.
He joined Horus and the other traitor legions during the Horus Heresy. He supervised the Iron Warriors as the bombed the shit out off Terra, and also the main siege. And he took much pleasure in taking Emperor's Palace walls down, when even traitor titan legions failed to do it, proving Dorn was wrong. However, Horus lost and they all fled to the Eye of Terror like little bitches.
Unknown to anyone else, Perturabo had always possessed a strange connection to the Eye of Terror- for some reason, he could sense it from anywhere in the galaxy, and he became convinced that it was constantly watching and judging his every action. The resulting inferiority complex wasn't really helped by the fact that when he tried ask others if they could see the Eye, they assumed he was hallucinating. (Ironically, he was actually the one to give the Eye its current name- before then, it was called Cygnus X-1.)
Iron Cage Trolling
But before fleeing he performed one of the greatest acts of trolling in the entire fluff, called the "Eternal Fortress". A trap set for the Imperial Fists who wanted to take revenge on Perturabo who claimed to be residing in the Central Keep of the Fortress. When the Imperial Fists DID manage to get to the keep, after going through twenty miles of killing ground, they found out the Central Keep was *plot twist* empty! This caused Rogal Dorn to become a normal man after getting trolled: Sad, broken and RAGED, but before the Imperial Fists even got out of the mess, they had get shot at for three weeks, before they are saved, by none other then the great heroes of the Imperium, the *cough* Ultrasmurfs *Cough*
The Iron Warriors obtained the gene-seed of hundreds of Imperial Fists and sacrificed it to the Chaos Gods, who showed their gratitude by elevating Perturabo to the position of Daemon Prince of Chaos Undivided.
Now, Perturabo is lazy, like many other Primarches, and hasn't really done anything but watched hentai in his Fortress of Hate, on some epic sounding Daemon World called "Medrengard". The Iron Warriors go on to be one of the most used Chaos Legions in Black Library Writing, while Perturabo goes on to... entirely drop out of sight.
UPDATE: Phil Kelly decided to throw Perturabo a bone and gave him a day in the spotlight in the new Codex: Chaos Space Marines. In 400.M32, he single-handedly annihilated the forge world of Toil in eight days. With Nurgle's help, he unleashed a machine-plague that transformed the planet's factories into walking monstrosities while causing Daemon Engine-spewing cables to burst out of the ground. This actually makes him the most deadly hacker to ever exist. About time he got off his daemonic ass.
